The ongoing investigation is into roughly $8.3 million in tax evaded, the CRA said.

The CRA said information from the Financial Transactions and Reports Analysis Centre of Canada (Fintrac), Canada’s anti-money-laundering watchdog agency, has played a “significant” role in the investigation. Fintrac gathers information on financial transactions, such as all transfers of $10,000 or more into and out of Canada.

“These search warrants show that our investments are paying off and we are starting to see results. Fighting tax evasion is a priority for our government,” Revenue Minister Diane Lebouthillier said in a statement.
